Hamilton creator and star Lin-Manuel Miranda made his debut on Twitter's live-streaming app Periscope June 21, offering some details about casting for the upcoming archive recording of the show, and teasing the upcoming Hamilton Mixtape, which he said is scheduled for a November release.

As previously announced, the Mixtape will consist of celebrity vocal artists singing numbers from Hamilton. Miranda played a segment and dared listeners to guess who it was.

He also revealed at original cast member Jonathan Groff will rearrange his movie shooting schedule in the next few weeks so he can play George III in the planned archive recording of Hamilton. Rory O’Malley, who currently plays the role, has agreed to stand down for the recording.

However, Miranda said “It’s going to exist but we don’t know what's going to happen with it” once it is recorded.

Miranda said he expects the new cast members for Broadway and the upcoming Chicago production will be “announced soon.” He said, “It’s all new folks, but you’ll know some of them.”

His Prizeo fundraising contest to benefit the Hispanic Federation has three days to go, and he urged listeners to ”take your shot” by entering to win one of two pairs of tickets to his final performance July 9, plus a visit to the after-party.

As for leaving the show, he said, “I feel fine. This is just a lull for me so I can finish and start writing new stuff.”

Regarding having Aaron Tveit as a guest for one of his #ham4ham concerts, he said, “Before I leave is all I’m gonna say!"

Miranda’s appearance on Periscope earned him more than 1 million “hearts.”
